Part Inspection in Batches

By | 2018-01-12T08:29:32+00:00 December 20th, 2017|3D Scanning|0 Comments

You can easily perform part inspections in batches and automatically generate inspection reports for each part using a Creaform HandyScan scanner, along with Geomagic Control X software. The first step is to capture your parts’ geometry with a metrology grade, certified scanner. Scan each part in the batch, and export an STL file. It’s handy to put all of the scans in one folder. The next step involves creating a master file that will be used for comparison and inspection. Once you’ve imported the CAD file into Control X, add the appropriate dimensions, tolerances, Datums, and GD&T information to the CAD model. This critical inspection information may also be seamlessly transferred from CAD into Control X. Next, choose the method of alignment for your scan, so that you can align it with the CAD model correctly. Although we typically use the datums called out on the manufacturing drawing, various alignment methods are available depending on the need. Once you have the scan aligned, create the types of analysis that will be performed and orient their corresponding views. Last, you can prepare your report by choosing which information you want to include. You will notice that with little effort, the analysis results along with their corresponding views are leveraged, automatically populated, and your inspection report is generated for this one scan. At this point, you’re ready to start your Batch Process. After choosing certain parameters, select the folder that contains the scans and Control X will import each scan one by one, align it to the CAD model, perform the study, produce analysis result, and generate the full inspection report for each scan...all without user interaction! As you can see, this is really leading-edge technology! Using a metrology grade scanner, and Geomagic’s Control X software, you can automate the creation of inspection reports in batches, with no human interaction.

Reverse Engineering a BMW Speaker

By | 2017-12-19T09:21:32+00:00 December 6th, 2017|3D Printing / Additive Mfg, 3D Scanning|0 Comments

Reverse Engineering has many purposes, one of them being to recreate parts or components that are no longer manufactured. With straight-forward mechanical components, this can be accomplished with a variety of measuring instruments. This task can quickly become more complex though, if the part takes on more of a freeform or ergonomic shape. To serve as an example, the president of our company recently had one of his speaker covers broken. Despite the fact that this is something that can be purchased, we decided to reverse engineer it with all the available tools here at Cimquest. The first step was to scan the part and capture as much as the geometry as possible. This was done with the Creaform HandyScan 700 scanner, which has a resolution of .2 millimeters. Next, we imported the scan into Geomagic Design X. This software allows us to interrogate our scan, and trace the outline of each feature that we need in order to recreate our CAD file. When we’re done, we end up with a fully-featured, editable CAD file that can be exported into a variety of CAD packages. In CAD, you are able leverage these fully editable features to make modifications and optimize your design. The last step is to 3D print our product as an end use part. In this case, we used our HP Jet Fusion 3D Printer, and produced the speaker cover in Nylon 12, which is knows not only for its outstanding mechanical properties, but also for its superior flexibility. The result? A recreation of the original product, with a few tweeks and modifications to suit the customers’ requirements! As you can see, having the right tools for the job makes a huge difference– from 3D scanning to reverse engineering software to CAD and 3D printing.

Reverse Engineering a 3D Pipe

By | 2017-12-21T09:14:21+00:00 September 20th, 2017|3D Scanning, Tech Tips|0 Comments

This blog article will illustrate how to extract the centerline of a 3D pipe with compound angles. Extracting the centerline of a 3D pipe that contains angles in 2 dimensions is not that complicated. However, when you have compound angles, and the tube is bending in the X, Y, and Z directions simultaneously, extracting the centerline can be quite challenging. For example, below we have a prototype of ½ of a bicycle handle, printed on the HP Printer, in Nylon 12. It contains bends in compound angles. Let’s say you don’t have the CAD file to work with and would like to extract the centerline, so that you can create a true CAD file, improve it, and then eventually create a manufacturing drawing . . . One solution to accomplish this is to use Geomagic Design X software and this is how it would work. First, you would need to capture the physical geometry of the handle bar using a 3D scanner and then export an STL file. Next, import the STL file into Geomagic Design X. Design X has a function called: Sweep Wizard. With a few clicks, it produces a fully editable feature tree to create this shape. But what is it actually doing in the background? The Sweep Wizard analyzes the mesh, identifies the diameter size that is being swept (or the profile), extracts the centerline of the sweep (or the path), creates a plane normal to one of the ends of the path and puts the profile on that plane, and finally takes that information and produces a the sweep as a CAD feature. You can then export this collection of features out to CAD, and make modifications or improvements as need and create my manufacturing drawing. As you can see, the task of reverse engineering a 3D pipe with compound angles just got a whole lot easier with Geomagic Design X software. With the click of a button, you are able to capture the design and export fully editable CAD features, which will assist you in creating even better products!

CMM Inspection without a Master Part

By | 2017-12-22T08:21:20+00:00 August 30th, 2017|3D Scanning, Tech Tips|0 Comments

Have you ever needed to inspect parts in a CMM, without having a master part? Automated CMMs can be a great time saver when inspecting parts on the shop floor. Traditionally, a master part is measured to generate a master data set. The same routine is then automated and used to measure each production part. Each production data set is then compared to the master data set to determine the actual size of the part and whether it is within user defined tolerances. But what if you don’t have a master part available, or one that was closely produced to drawing nominal? This is where the CMM Master can be a great solution. The CMM Master, based on the Renishaw Equator platform, is a portable, automated CMM, calibrated for high production shop floor inspection. In conjunction with the Verisurf software, it is volumetrically error mapped to increase the traditional Renishaw Equator accuracy down to .0005”. Here you see the CMM Master running an automated measurement routine. When it’s done, it automatically generates a date and time stamped report. One thing that makes the CMM Master unique is that a master part is not required in order to perform on the fly measurements. You can remove the part that was originally aligned on the machine and in use by the CMM Master, and replace it with a completely different part. Fixture the new part to the platen, but do not align it or calibrate it in any kind of way. Then you can use the Measure Module in the Verisurf software to simply tell it what type of geometry you’re looking to measure and use the probe to start collecting data. When complete, it provides the measurements you were looking for, all without having to first digitize a master part. This is a great time saver. As you can see, the CMM Master along with the Verisurf software is a great tool that not only easily creates automated measurement routines, but also captures on the fly measurements, without even having a master part.

Simultaneous Synchronized Scanning

By | 2017-12-22T08:35:53+00:00 June 28th, 2017|3D Scanning, Tech Tips|0 Comments

This blog post is going to show you how to scan a mid-size part with tiny features. When scanning a model, you're usually faced with the decision of using a scanner that either has a large scan envelope and good resolution, or a scanner that has a small scan envelope with high resolution. But what if you needed the best of both worlds, that is, to capture both a larger part with small fine details? One way to achieve this is to run two scanners simultaneously, and synchronize them to the same turntable. The Geomagic's Capture scanner has an accuracy of about .0035" and is good for scanning mid-size objects. When scanning a model, it's able to pick up the majority of the geometry, but the small fine features get washed out. This is where simultaneous synchronized scanning comes in. You can synchronize Geomagic's Mini-Capture scanner to the same turntable that is aligned to the Capture scanner. The Mini-Capture has a smaller scan envelope, but an impressive accuracy of about .0015." This is what is needed for capturing the fine details on a small part. To run the scans simultaneously, press the Scan button and the turntable moves. Each scanner takes turns scanning and then those same two scans are automatically aligned to each other. This process continues until the table turns a full 360. In the example below this we ended up with 32 aligned scans coming from to separate scanners with different accuracies. At this point, you just need to delete the geometry that you don't need from each scanner so that the number of points is reduced and you will end up with one complete high-quality scan! As you can see, Simultaneous Synchronized Scanning is a great way to capture parts where you need to leverage size, but at the same time capture very small fine details.

Geomagic Design X

By | 2017-12-22T08:39:04+00:00 June 21st, 2017|3D Scanning|0 Comments

With Geomagic Design X software you can easily produce a fully featured, editable, native CAD model, directly from a scan. What is Design X? Design X software is a tool that enables you to recognize geometrical features on a scan, utilize them to create CAD features, then transfer that tree of features directly out to the feature tree of your CAD system. Let’s break this process up into three stages: Auto Segment, Feature Extraction, & LiveTransfer to CAD. Auto Segment Auto Segment in Design X allows you to split the polygonal mesh into regions, created by grouping adjacent polygons with similar curvature. As you hover your mouse over each region, Design X displays the geometric shapes that have been identified, like a plane, cylinder, cone, etc. Feature Extraction Once you have all your geometrical regions mapped out, your next step is to extract and create the CAD sketches and features. To do this, start a mesh sketch either directly on a planar region, or a CAD plane, then offset the plane to the location where you want to extract a slice of the polygonal mesh. At this point you will be creating your 2D Sketch entities. You can use that polygonal mesh profile as a guide to get the correct shape and size. Because this part is symmetrical from left to right, you will capture the design intent by adding the centerline. You can double click on the mesh profiles and Design X extracts true analytical geometry. You can do this with lines, as well as with arcs, circles and so forth. At any point you can interrogate your mesh by using the measure tools. If you want to average multiple mesh profiles, you can fit the geometry and extract an average shape. This would be a good option if the part was warped, used, or broken. Lastly, you can mirror the entities to the other side and clean up your sketch and dimension values, and add sketch relations so as to have one clean closed loop. If you want to see how close your CAD geometry matches the polygonal mesh geometry the Deviation check will show green in the areas that are within the tolerances you set. Red indicates that your CAD model has more material than the scan, and blue means that the CAD is under the polygon mesh. Live Transfer to CAD Now you can transfer the list of CAD features over to your CAD software. Just pick the CAD software that you’re transferring to and the version. SolidWorks will open up, and start auto-building your feature tree. Once the export is complete, you can modify your SolidWorks file natively, as if it was created in SolidWorks itself. Geomagic Design X is very powerful software. It allows you to take point cloud data or a polygonal mesh, and enables you to identify geometric shapes, interrogate the polygonal mesh, build CAD features and sketches using the poly mesh as guide. And last but not least, you take all [...]

Reverse Engineering Sheet Metal to a Flat Pattern

By | 2017-05-08T09:31:52+00:00 May 8th, 2017|3D Scanning|0 Comments

Today we are going to talk about how to reverse engineer a used sheet metal part back to its original flat pattern. This can be challenging at times, since sheet metal parts tend to bend and distort with normal use. Geomagic Design X can assist you in interrogating the geometry of the part, and reverse engineering it back to the original un-warped shape. After scanning the part, you can import the resulting point cloud into Geomagic Design X and clean up scan file. Next, convert the points to a polygonal mesh, and Auto Segment the mesh. By auto-segmenting the mesh, Design X creates regions made up of polygons that have similar curvature values. Thus, it becomes easy to identify and interrogate geometric shapes. You can then use these regions to create and establish your Datums. At this point, you can start reverse engineering your CAD file by tracing over the mesh profiles, and creating real 2D and 3D geometry. Design X keeps a CAD history tree of everything you’re doing. When you have captured enough information from your polygonal mesh, you can then export your work to your CAD software. In CAD, you can complete your design by converting your solid model into a sheet metal model, add additional required geometry, and validate it with FEA software to ensure that it will withstand the loads that it will be subjected to. Lastly, you can generate the flat pattern and from there you will able to create your manufacturing drawing. As you can see, by using the right tools, it is possible to reverse engineer a used sheet metal part back to the original sheet metal flat pattern, and produce a complete manufacturing drawing.

Improving Aesthetics of a Scanned Mesh

By | 2017-04-10T09:10:21+00:00 April 10th, 2017|3D Scanning, Tech Tips|0 Comments

In this blog post we will discuss how to improve the quality of your STL to produce better 3D Printed parts. The STL, or Stereo Lithography file format, is widely used for rapid prototyping, 3D Printing, and CAM. An STL file describes the surface geometry of a 3D object by triangulating the vertices on each face of the object. At times though, the STL file may contain errors, small holes, imperfections, and blemishes as shown below. These imperfections may happen if the file was produced by scanning a used or worn part. So how do you go about modifying the STL file, and optimizing it, to produce a better quality 3D Printed part? One solution is to use Geomagic Wrap. It has many powerful easy-to-use tools that enable you to improve the cosmetics of the model by modifying the mesh structure underneath. Let me show you a few of these tools. First, you can easily remove the spikes, or pyramid shaped polygons from the mesh and smooth them out by using the Spike Removal tool. Next, for the sections of the model that are really sloppy, you can simply delete the polygons by using the Manifold Open tool to quickly get rid of the residual polygons. Then, fill the hole back in using the appropriate curvature conditions. A quick way to delete features and fill them back in is by preselecting a group of triangles, and using the Defeature tool. Not only does this patch the resulting hole, but the new polygons match the curvature of the surrounding geometry. Any noise that was produced in the scanning process can also be filtered out and deleted pretty quickly by using the Reduce Noise tool, and setting the appropriate parameters and smoothness level. As you can see, by using a few of the many powerful tools in Geomagic Wrap, in a short time you can take a poor looking STL file, optimize the STL mesh, and turn it into something aesthetically pleasing, while maintaining the integrity of the original shape.
